ScriptManager.RegisterStartupScript Method (Page, Type, String, String, Boolean)

Registers a startup script block for every asynchronous postback with the ScriptManager control and adds the script block to the page.

Namespace:  System.Web.UI
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

public static void RegisterStartupScript(
	Page page,
	Type type,
	string key,
	string script,
	bool addScriptTags
)

Parameters

page
Type: System.Web.UI.Page

The page object that is registering the client script block.

type
Type: System.Type

The type of the client script block. This parameter is usually specified by using the typeof operator (C#) or the GetType operator (Visual Basic) to retrieve the type of the control that is registering the script.

key
Type: System.String

A unique identifier for the script block.

script
Type: System.String

The script to register.

addScriptTags
Type: System.Boolean

true to enclose the script block with <script> and </script> tags; otherwise, false.

You use this method to register a startup script block that is included every time that an asynchronous postback occurs. To register a script block for a control that is inside an UpdatePanel control so that the script block is registered only when the UpdatePanel control is updated, use the RegisterStartupScript(Control, Type, String, String, Boolean) overload of this method.

If you want to register a startup script that does not pertain to partial-page updates, and if you want to register the script only one time during initial page rendering, use the RegisterStartupScript method of the ClientScriptManager class. You can get a reference to the ClientScriptManager object from the ClientScript property of the page.
